Nissan 370Z Z34 Roadster
RH Front Door Jamb / Contact / Ajar Switch

This used switch has the molded identifier 7420E1 visible on the actual item. Its physical design corresponds closely with Nissan door-jamb switch service-family 25360-AD000, with catalogue supersessions 25360-4Z000 and 25360-EN00A.

Important: the donor VIN is not published in the source listing. We therefore do not represent the wider catalogue cross-reference below as a VIN-confirmed guarantee for this individual used switch. If you are unsure, send your full 17-character VIN and a clear photograph of your existing switch through eBay Messages before purchasing. Fitment should be verified from VIN, service-number family, connector, mounting point and physical configuration — not registration or appearance alone.

Part Identification

Exact polymer/elastomer material grade is not marked on the component and is therefore not claimed. 7420E1 is treated here as the visible molded identifier rather than being represented as a confirmed Nissan service number without VIN verification.

🚘 Correct Vehicle Body-Style Reference

The listing identifies a Nissan 370Z Z34 Roadster. The following references intentionally show the correct 2-door Z34 Roadster / convertible body style. They are reference vehicles only and are not the donor vehicle.

📍 Where Is This Switch Fitted?

The door-jamb/contact switch is mounted to the vehicle body in the RH door aperture / centre-pillar area. When the door closes, the door presses the rubber/plunger section inward. Opening the door releases the plunger.

This location guide is deliberately used instead of copying a random internet close-up: a visually similar switch fitted to a different Nissan model could show a different mounting position and increase the risk of an incorrect order.

⚙ What Does It Control?

This component supplies the vehicle with an electrical door-open / door-closed state. On applicable vehicles that information is used for functions such as the interior/courtesy lamp and door-ajar status. Additional body-control behaviour can vary with model, market and equipment level, so functions not confirmed for the individual VIN are not promised here.

🔎 Possible Symptoms of a Faulty Door-Jamb Switch

• Interior/courtesy lamp does not illuminate when the RH door is opened.
• Courtesy lamp remains illuminated after the door has been closed.
• Intermittent or incorrect door-open / door-ajar indication.
• Door-state functions work only when the switch or door aperture is moved.
• Possible battery discharge where a faulty door-state signal causes lighting to remain commanded on.
• Other door-state-dependent body functions may behave inconsistently on suitably equipped vehicles.

These symptoms can also be caused by wiring, connector, adjustment or body-control faults. Diagnose the circuit before replacing additional parts.

⭐ Why Choose a Factory-Original Used Part?

A factory-original component was designed around the vehicle manufacturer's connector geometry, mounting footprint, plunger travel and intended installation. Very low-cost pattern copies can differ in connector keying, housing dimensions, plunger travel, sealing and material quality.

Reusing a serviceable factory-original component can therefore provide an excellent balance of correct design, value and environmental benefit. On selected automotive components, buying used can save up to 70% compared with the price of an equivalent new component; the actual saving naturally varies with the part and current new-part pricing.

✅ Primary Vehicle Reference

Catalogue Service-Family Cross-Reference

A catalogue-family entry means the service-number family appears against that model/year range. It does not establish that every trim, market, body position or individual VIN uses this exact switch.

❌ Do Not Order This Part If...

• Your VIN lookup returns a different door-jamb/contact switch service number.
• Your original connector keying differs from the actual-item photographs above.
• Your original switch uses a different mounting eye, footprint or plunger arrangement.
• You are looking for a door latch/lock actuator, electric-window switch, bonnet switch or luggage/boot switch.
• Your model/derivative is not supported by the appropriate catalogue or VIN lookup.
• You are choosing the part only because it appears visually similar.
• You have not checked the existing switch where the original number or configuration is available.

Unsure? Send the full 17-character VIN and a clear photo of the old part through eBay Messages. We would rather verify it before purchase than have you order the wrong component.

🔧 Fitting Guide

The following is a practical installation overview, not a substitute for the model-specific factory repair procedure.

1. Confirm compatibility first. Check the VIN, original service-number family, connector and mounting geometry.
2. Park the vehicle securely, switch the ignition off and keep the key away from the vehicle.
3. Open the RH door and identify the body-mounted plunger/contact switch in the door aperture / centre-pillar area.
4. Compare the replacement part with the original before disconnecting anything.
5. Photograph the original connector orientation if useful.
6. Use the driver/bit that correctly matches the existing fastener. Do not force an incorrect tool.
7. Remove the retaining fastener and ease the switch outward sufficiently to access the connector.
8. Release the electrical connector latch carefully without pulling on the wiring.
9. Connect the replacement switch and ensure the connector locks positively.
10. Seat the switch squarely in its original mounting position.
11. Refit the fastener to the specification required by the applicable factory repair information. Do not overtighten against the plastic housing.
12. Test the RH door open/closed state and courtesy-light operation before completing the job.
13. If the fault remains, diagnose the connector, harness and body-control circuit rather than repeatedly replacing parts.
